Inheritance attributes acquired via biological heredity from the parents
Artificial selection the process used in selective breeding.
Selective breeding the process through which humans use naturally occurring genetic patterns to pass desired traits on to generations.
Fossil record refers to all fossils that have been found since the study of fossils began.
Mutations are random changes in DNA that act as another way organisms evolve.
Interdependence of Organisms dependence between abiotic and biotic factors
Ecosystem organisms interacting with their environment
